CD-4 was responsible for major improvements in phonograph technology including better compliance, lower distortion levels, pick-up cartridges with a significantly higher frequency range, and new record compounds such as Q-540, which were highly anti-static.

But when a record was called quadradisc it was always a CD-4 record.

UD-4 is the process of modulating QMX onto a record with a process similar to CD-4, but also matrix encoded.

Despite the tape cartridge box art sharing the Quadradisc record logo, a planned CD-4 quad vinyl version of the 3 record set had to be scrapped, due to engineering issues with master tapes that prevented JVC from cutting a stable master to meet strict CD-4 format specifications.

In the CD-4 system, the quadraphonic audio was divided into left and right channels which were recorded orthogonally in the vertical plane of the disc groove, which is the case with normal stereo.

The developing ingredient is a paraphenylene diamine-based chemical known as CD-4.

Lymphocyte T-Cell Immunomodulator is a potent regulator of CD-4 lymphocyte production and function.

UD-4 was less critical in its set-up than CD-4, because the carriers did not have to carry frequencies as high as those found in the CD-4 system.

But CD-4 ( and quadraphonic audio in general ) failed due to late FCC approval of FM quadraphonic broadcasting, the improvements CD-4 engendered spilled over into, and substantially improved, the production of conventional stereo LP records.

Simply put, CD-4 consists of four recorded signals ( LF, LB, RB, RF ) and the following coding matrix, similar to FM broadcast stereo multiplexing.

Some cartridges had frequency response above 30 kHz for use with CD-4 quadraphonic 4 channel sound.

RCA then began releasing quadraphonic vinyl recordings in 1971, primarily of classical music, in the CD-4 format developed by Japan Victor Corporation ( JVC ), and made commercially practical by Quadracast Systems Inc. ( QSI ).

" The CD-4 format required a special cartridge that had a ± 1 db frequency response out to 50 kHz, a CD-4 demodulator which decoded the difference between the front and rear channels from a 30 kHz subcarrier, four separate amplifier channels, and four separate speakers for the left and right front and left and right rear.

Both the CD-4 Quadradisc and Quad-8 tape cartridge systems were true discrete 4-4-4 quadraphonic systems.

The third major format for 4-channel vinyl LPs, known as CD-4 or Quadradisc, was devised by the Japanese JVC Corporation along with its United States counterpart, RCA.

A high-frequency " carrier wave " instructed a " CD-4 demodulator " on how to separate the four sound channels within the vinyl album.

Compatible Discrete 4 ( CD-4 ) or Quadradisc ( not to be confused with compact disc ) was introduced in May 1972 as a discrete quadraphonic system created by JVC and RCA.

A typical CD-4 system would have a turntable with a CD-4 cartridge, a CD-4 demodulator, a discrete four-channel amplifier, and ( ideally ) four full-range loudspeakers.

Some manufactures built the CD-4 demodulator into complete four-channel receivers.

Quadradiscs / CD-4 records were seldom called quadraphonic.

The other two contained only band-limited localization information, and were encoded with carriers similar to the CD-4 system.

* Various Quadraphonic encoding methods: CD-4, SQ, QS-Matrix, and others.
